MDZhB featured in BBC Future’s “Best of 2017”

Many thanks to SWLing Post contributor, Golan Klinger, who shares the following article which was elected “Best Of 2017″ on the BBC Future website:

“MDZhB” has been broadcasting since 1982. No one knows why.

In the middle of a Russian swampland, not far from the city of St Petersburg, is a rectangular iron gate. Beyond its rusted bars is a collection of radio towers, abandoned buildings and power lines bordered by a dry-stone wall. This sinister location is the focus of a mystery which stretches back to the height of the Cold War.

It is thought to be the headquarters of a radio station, “MDZhB”, that no-one has ever claimed to run. Twenty-four hours a day, seven days a week, for the last three-and-a-half decades, it’s been broadcasting a dull, monotonous tone. Every few seconds it’s joined by a second sound, like some ghostly ship sounding its foghorn. Then the drone continues.

Once or twice a week, a man or woman will read out some words in Russian, such as “dinghy” or “farming specialist”. And that’s it. Anyone, anywhere in the world can listen in, simply by tuning a radio to the frequency 4625 kHz.

It’s so enigmatic, it’s as if it was designed with conspiracy theorists in mind. Today the station has an online following numbering in the tens of thousands, who know it affectionately as “the Buzzer”. It joins two similar mystery stations, “the Pip” and the “Squeaky Wheel”. As their fans readily admit themselves, they have absolutely no idea what they are listening to.[…]

The Ghostly Radio Station that No One Claims to Run

There is a great article by Zaria Gorvett in the BBC Future online magazine concerning several transmitting stations which have baffled folks for decades.

Here is a brief introduction:

In the middle of a Russian swampland, not far from the city of St Petersburg, is a rectangular iron gate. Beyond its rusted bars is a collection of radio towers, abandoned buildings and power lines bordered by a dry-stone wall. This sinister location is the focus of a mystery which stretches back to the height of the Cold War.

It is thought to be the headquarters of a radio station, “MDZhB”, that no-one has ever claimed to run. Twenty-four hours a day, seven days a week, for the last three-and-a-half decades, it’s been broadcasting a dull, monotonous tone. Every few seconds it’s joined by a second sound, like some ghostly ship sounding its foghorn. Then the drone continues.

Once or twice a week, a man or woman will read out some words in Russian, such as “dinghy” or “farming specialist”. And that’s it. Anyone, anywhere in the world can listen in, simply by tuning a radio to the frequency 4625 kHz.

Shortwave Radio Recording: “The Buzzer” on 6,998 kHz

UVB-76-Buzzer

Screen capture of the Web SDR waterfall tuned to 6,998 kHz.

On Friday, Andrea Borgnino, tweeted that he could once again hear “The Buzzer” on 6,998 kHz. Of course, during the day, I couldn’t hear  the signal from my home in North America.

I could, however, easily hear the signal via the University Twente Web SDR in the Netherlands.

Here’s my recording:

As I’ve mentioned before, I’m pretty sure this is simply a pirate having a little fun relaying UVB-76 audio on 6,998 kHz.

My buddy, Andrea Borgnino, recently heard UVB-76 (The Buzzer) on 6,998 kHz with his Elecraft K3 in Italy. Check out this short video:

While the audio sounds identical to that of UVB-76’s on 4,625 kHz. I strongly suspect this is simply a pirate radio station relay–especially since it’s broadcasting just below the 40 meter ham radio band. Either way, it’s a great catch! Thanks for sharing, Andrea!
